New headphones

I am looking to buy some new headphones, with a budget of around £250 pounds. I am new to this forum and have read other post and you guys seem very helpful.

I will mostly be using the headphones for watching films, but not all the time. The music I often listen to is rock, stuff like ac/dc, status que etc. I was going to purchase some Beats headphones as they seem to get very good reviews, but since finding this forum you guys don't seem so keen.
